Some sandals (6)
I believe the answer is:
slides
'some sandals' is the definition.
(I know this)
This is the entire clue.
(Other definitions for slides that I've seen before include "Sloping chutes in playgrounds" , "Pieces of glass under the microscope" , "Pieces of glass for study of specimens" , "Sloping chutes in the playground" , "Slips, slithers" .)
